  "account": "The air quality in Singapore is expected to remain between high moderate and low unhealthy levels over the next 24 hours, according to the National Environment Agency (NEA) advisory issued on September 6. The 24-hour Pollutant Standards Index (PSI) ranged from 73 to 87 at 6pm on the same day, as the central region's PSI peaked at 103 at 7pm on September 5, previously unhealthy levels. The readings in the north, south, east, and west areas remained in the moderate range. When the PSI is between 101 and 200, the air quality is considered unhealthy, and the public is advised to limit outdoor activities. PSI values between 51 and 100 indicate moderate air quality, while readings of 0 to 50 fall within the \"good\" range. Fair and windy conditions were observed in Singapore on September 6, with dry weather prevailing in the region. Smoke plumes from fires in Sumatra and West Kalimantan continued to drift towards Singapore, posing a continued risk of smoke haze affecting the city-state if the fires persist. NEA started issuing daily haze advisories on September 4 when the PSI in Singapore's central region entered the unhealthy range, marking the first time since 2023 that the PSI reading in the city-state reached this level due to haze.",
